Google Document Auto Upload

Hi, Currently I have an enterprise system (SAP) that can deliver an .xls report to my computer on a daily basis. I want a program that can automatically upload that .xls to google docs. It would have the same name each day. Ideally I could use the program multiple times by filling in these options. Original Document: (This is my original .xls) gDoc: (name of gdoc to load too) frequency: (6 hours, 12 hours, daily, weekly) thanks! Dave
